WATER-HEATER AND PIPE-CLEANING APPARATUS.

SEECIFICATION forming part of Letters Patent No. 67 7 ,859, dated July 9, 1901.

Application tiled September 14, 1900. Serial No. 29,999. (No model.)

To all wil/0m it) may con/cern."

Beit known that we, THOMAS E. COOK and GEORGE J. STRENG, citizens of the United States, residing at Detroit, in the county of lVayne, State of Michigan, have invented certain new and useful Improvements in Water- I-Ieaters and Pipe-Cleaning Apparatus; and we do'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, ref.- erence being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a water-heater and pipe-cleaning apparatus; and it consists in the construction and arrangement of parts hereinafter more fully set forth, and pointed out particularly in the claims.

The object of the invention is to produce a portable apparatus in which water may be heated to any desired temperature and in which the arrangement is such that the water after being heated may be subjected to an air-pressure to force the heated water through pipes which may be attached thereto for the purpose of cleaning them. Y

The above object is attained by the device illustrated in the accompanying drawings, in which- Figure lis a central vertical section through the apparatus embodying our invention. Fig. 2 is a horizontal section as on line 2 2 of Fig. 1.

Referring to the characters of reference, 1 designates a watermeceptacle, which is preferably cylindrical in form and is mounted upon a suitable base 2. receptacle is a pressure-gage 3 to indicate the pressure within said receptacle. Arranged in a circle within said receptacle is a series of vertical hot-air fiues 4, whose lower ends open through the bottom of said receptacle, as shown at 5, and whose upper ends are provided with elbows 6, which direct said tlues outwardly through the side wall of the water- Located at the top of said at the base of the receptacle, allowing the passage of hot air from the lower end thereof.

Communicating with the upper end of the water-receptacle is a water-supply pipe 10, having a controlling-valve 1l. Also communicating with said receptacle is an airpipe 12, to which an air-pump (not shown) may be attached, said pipe having a controlling-valve 13. The discharge-pipe 14 communicates with the bottom of the water-receptacle and is provided with a valve 15. Through said discharge-pipe the contents of the heater may be discharged and forced through a series of pipes or into any receptacle with which said pipe 14 may be connected.

Any suitable burner 16 or other heating device whereby a flame may be generated is placed under the bottom of the water-receptacle and the heat produced by the iame passes upward through the flues 4 and is discharged from the upper end of said iiues into the air-space 9 between the water-receptacle and the hood 8. The heated air occupies said space until forced out by the pressure at the top,'so that the entire exterior surface of the water-receptacle is subjected to theaction of the heated air, as well as the inner surface of the iiues 4. It will be understood that the water in the chamber 17 of the receptacle surrounds the tubes 4, so that said tubes are entirely submerged. The presence of the heat within saidrtubes, which pass through the water, and the contact of the heated air against the exterior wall of the water-receptacle tend to quickly heat thewater within said receptacle to a high temperature.

The heater being portable enables it to be carried to a bath-room, if desired, after the `water has been heated and the contents of .in the bath-room tends 4to heat said room should it be cold.

Where it is desired to force the heated con; tents from the water-receptacle under pressure, any suitable air-pump is connected to the pipe l2 and such pressure created within the receptacle of the heater as may be desired, the valve 13 serving to retain said pressure.

Ico

cleansing solution may be employed, which when heated to ahigh temperature and forced from the heater under pressure will serve to thoroughly cleanse the pipes to which the heater may be connected.

For the purpose of closing 'the opening at the bottom of the air-space 9 between the hood and receptacle a transverse plate 1S is located therein, having a series of apertures 20. Mounted upon said plate is a rotary ring or damperplate 2l, having apertures 22, which register with the apertures of the plate 1S. Attached to said ring or damper is an operative handle 23. By means of said handie the dampenplate 2l may be rotated to close the openings in the plate 18 and confine the heat within the air-space 9. When said damper-plate is moved to cause its apertures to register with those in the plate 18, openings are formed which allow of the unobstructed passage of heated air from said air-space at the bottom. I

A- Water column or gage 24 is connected with the Water chamber or receptacle, so as to in- 1 dieat'e at all times the Water-level therein.

Suitable handles 25 are provided to enable f "the heater to be moved from place to place.

Having thus fully set forth our invention, what We claim as new, and desire to secure by Letters Patent, is-

1. In a Water-heater and pipecleaning apparatus, the combination of the Water-receptacle, a series of iiues passing upwardly 'through the bottom of said receptacle and discharging through the side Wall thereof, a hood embracing said receptacle and spaced therefrom forming an annular air-space between thereceptacle and hood opening at its lower end, induct Water-pipe and an induct pressure-pipe communicating with the inte- 'rior of said receptacle, an educt-pipe leading 'from said receptacle and a burner or heater located below the bottom thereof.

2. The combination of a Water-receptacle, 'having a series of vertical flues passing upjwardly through the bottom thereof and provided with right-angled bends which direct @the upper ends of the duesv through the side `iwall of the receptacle, a hood forming an airspace into which said tlues discharge, said air-space being closed at the top and normally :open at the bottom and communicating di- `rectly with the exterior air, means for regulating the bottom opening of said air-space, 'a heater communicating with the lower end of said dues, waterinduct and ed uct pipes and an eXteriorpressure-pipe communicating with gthe interior of said receptacle.

In testimony whereof we sign this specification in the presence of two witnesses.
